Private beta, imminent
AI phone reception for restaurants, inns and shops. Around the clock, AI answers in a natural voice, writes bookings to Google Calendar, and records, summarizes and notifies on every call. Underneath sits a conversation platform with a public API and SDK — partners build their own products on top.

● Features
TararaWe take on the work,the whole of it.
Bookings settled mid-conversation
It confirms date, party size, name and contact, then writes straight to Google Calendar. Alerts to Slack, SMS and LINE so nothing slips.
Multilingual for inbound
Starting JP/EN, one engine extends to more languages. A free-flowing conversation no scripted IVR can match.
Recorded, safe, disclosed by design
Every call transcribed and summarized. AI reception is disclosed automatically at the start, and a safety layer inspects every tool call.
Setup is just call forwarding — same number, no construction.
